Pcm tdm active slots: slot mask order · case 03

Active TDM mask is interpreted with reversed slot numbering.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Stipulated TDM PCM extractor: active mask bits name ascending physical slots; ignore mask bits above slot count and reject incomplete physical frames.

Why this case matters

Offline PCM interchange uses these exact bounded packet and sample representation decisions.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
oracle 1	`[[0, 2], [[10, 30], [1, 3]]]`	`[[1, 3], [[20, 40], [2, 4]]]`	Failed
